[mythtv-users] Mythbuntu 10.10 upgrade broke VDPAU

[Jon Whitear]

Hello folks,

I recently upgraded my frontend-only machine from Mythbuntu 10.04 to 10.10. Now playback with vdpau is broken. Fortunately playback with the "normal" profile is fine. Here's what the log says when I try to play back with VDPAU enabled:-

I gather that this usually indicates the absence of of VDPAU libraries. I have removed and reinstalled the nvidia-current package (which is supposed to include the library) and tried installing from the Nvidia-supplied installer. I've also tried fixing a link like so (all suggestions served up by google.)

sudo mv /usr/lib/libvdpau_nvidia.so /usr/lib/libvdpau_nvidia.so.OLD
sudo ln -s /usr/lib/nvidia-current/vdpau/libvdpau_nvidia.so /usr/lib/libvdpau_nvidia.so

jon at fe2:~$ ls -al /usr/lib/nvidia-current/vdpau/

The Xorg log makes no mention of VDPAU. I have a 9500GT with 1GB RAM. I've run out of ideas. Any help is appreciated.

Cheers,

Jon
